"No Output for loop?"
% I want to create a loop for all number combination from 1 to 10^4 for a^3+b^3=c^3
% My Script does not work. There is no Output and no errror code.
% When i change i to 2 then it works but why not when i use 3 for i
% Please help me to fix my problem
% Thank you
n = 10^4;
i = 3;
for a = 1:n
for b = 1:n
for c = 1:n
if (((a^i)+(b^i)) == (c^i))
result = ['Bingo ' 'For a: ' num2str(a) ' For b: ' num2str(b) ' For c: ' num2str(c)];
disp(result)
end
end
end
end

You could could potentially display 1.000000000000000e+12 values. I would seriously reconsider doing that.
The reason nothing is displayed is because none of the values tested meet the condition of your if statement. In fact, the only integer solution to this equation is a=b=c=0 (proved by Fermat and perhaps Euler).
